Ashcroft 1130 series differential pressure gauges feature four models offering different pressure ranges and maximum static pressures. Each Ashcroft 1130 series differential pressure gauge is solidly constructed with a stainless steel case and a choice of aluminum, brass, or stainless steel body materials. These analog gauges are available with dials ranging from 2 to 6 inch in size. Connections can be 1/8 or 1/4 inch NPTF and connections can be located inline, on the back, or on the bottom of the gauge. Explosion-proof models are available. Ashcroft Type 1130: The Ashcroft Type 1130 differential pressure gauge uses a piston actuated design where small migration of the process media is permissible. Available in pressure ranges from 0-5 psid to 0-150 psid (or equivalent), the Ashcroft Type 1130 differential pressure gauge is recommended for high differential and high static pressures up to 6000 psi.
